Epoxy/polyester powder coating

Epoxy/polyester powder coating About

Introduction

Product Description

This series of products uses polyester resin and epoxy resin as the main base material to make thermosetting powder coating.

Product Features

• Good adhesion, excellent mechanical properties such as impact resistance;
• Good leveling and gloss;
• Strong chemical resistance and corrosion resistance;
• Better heat resistance and light resistance stability than pure epoxy powder.

Special effects

Various wrinkles, metal, pearlescent effects and mixed colors, etc.

Application areas

Suitable for coating of various indoor products, widely used in any indoor purposes such as furniture, household appliances, industrial equipment, sports equipment, toys, hardware machinery, store shelves, lamps, etc.

Transportation packaging

Carton packaging, lined with two layers of polyvinyl chloride plastic bags, net weight of each box is 20kg. Non-hazardous items can be transported in various ways, but should be kept away from direct sunlight, moisture and heat, and contact with chemicals.

Hygiene and safety

Operators should wear dust masks during use to avoid inhaling dust and minimize long-term contact between skin and powder coating. Paint attached to the skin can be washed with soap.

Powder properties

Specific gravity	1.41.8g/cm3 (depending on the formulation and color)
Particle size	Depending on the purpose, the standard type has an average particle size of 3540 microns, less than 10 microns powder <10%, greater than 100 microns powder <0.5%.
Volatile matter	<1%
Softening point	6095 varies depending on the color gloss
Storage stability	Epoxy/polyester powder coatings should be stored in a dry, ventilated room below 35, and avoid direct sunlight. If stored in an air-conditioned room, the powder must be stored at room temperature or the same (temperature) as the spraying equipment before use to avoid moisture. Under this condition, the powder can be stored stably for 12 months. If it exceeds the period, it must be re-tested. If the result meets the requirements, it can still be used. Note: For low-temperature curing types and powders with a gloss of less than 40% (60), the storage temperature should be below 30.

Curing conditions	200/10 minutes is recommended, and it can also be designed according to user needs: 140/30 minutes, 160/20180/10

Superior Protection and Aesthetic Versatility

Epoxy/polyester powder coating provides exceptional protection against weathering, UV radiation, and chemicals while enhancing the appearance of metal objects. With options for finish and color customization, this coating meets both functional and decorative standards. Its formulation ensures long-lasting performance even in demanding environments, making it a preferred choice for industrial applications across various sectors.


Efficient and Reliable Application Process

Application is achieved through electrostatic spray or fluidized bed methods, promoting uniform coverage and strong metal adhesion following appropriate surface pretreatment. The coating cures at 150C-200C, forming a robust film of 60-120 microns. This quick and effective process results in outstanding finish quality, ensuring consistency and reliability for large-scale industrial use.
